chip,

if you're a mahoromatic fan, you might enjoy this 
portion of my cel gallery. http://cels.stage-
on.com/mahoromatic/

as for dealers, there are no specific dealers who 
hold gluts of mahoro cels, or anything where 
she's not holding bowls of salad. :P really nice 
mahoromatic cels are pretty uncommon, as you 
probably know. just gotta be patient and hunt 
them out!

there are other collectors who have some very 
exceptional mahoromatic cels, if you're 
interested.
